The Cartographers’ Guild is a forum created by and for map makers and aficionados, a place where every aspect of cartography can be admired, examined, learned, and discussed. Our membership consists of professional designers and artists, hobbyists, and amateurs—all are welcome to join and participate in the quest for cartographic skill and knowledge.

Although we specialize in maps of fictional realms, as commonly used in both novels and games (both tabletop and role-playing), many Guild members are also proficient in historical and contemporary maps. Likewise, we specialize in computer-assisted cartography (such as with GIMP, Adobe apps, Campaign Cartographer, Dundjinni, etc.), although many members here also have interest in maps drafted by hand.

Looking for a Venus base

Hi,

I want to do a Venus map for my game but I can't find a proper base for it. I need a map of Venus with altimetry/topography with a good accuracy. I've just found some maps with false colours (flashy blue, yellow and red) and it's not very accurate...
There are a lot for Mars, but not for Venus.

Oh! I used to work on classic surface maps. But another format will do.

Has anyone seen toff recently? He had what looked like a radar surface map of Venus for his Venus Transit Map, but I don't recall if he said where it came from.

If that false color image is of sufficient resolution, you might be able to remap the colors to a more usable grayscale heightmap. As I recall, there's a topo made from Magellan data that uses a rather garish hypsometric scheme. If that's the one you have, then the reds are high altitude, the blues are low altitude, and the grays are areas where no data was captured. I considered using that image to get a displacement map for a 3d model of the planet, but I never had cause to look beneath the clouds, so it's sitting in one of my archives somewhere. I seem to remember that it was quite low-res, though, so I'd have had to do some pretty serious processing on it to get a usable texture, anyway.

And yeah, if your game is hard sci-fi you will need to do some serious thinking on that base. Even if it's a soft sci-fi setting, consider a city on the talles mountains, and even then a well protected one - thick walls, dome shapes to provide pressure resistance, etc.

Thanks a lot everyone! I had not looked on the guild news for quite a month.
Actually, I've already found quite good venus maps and I have worked on my elzevir venus map since then (but it's not finished).

I'm a scientist, so I know quite well about the harsh conditions on Venus atpollard. But my Elzevir's world is a kind of uchronia, so I stated that Venus and Mars were suited for life (but with certain conditions nevertheless). Venus and Mars are in the habitable zone and both had know an era (sometimes very short) with surface water bodies and a thicker (for Mars) or less carbonated atmosphere (for Venus).
